    Hot Rolled Strip Steel

    Tata Steel offers a choice of hot-rolled heat-treatable steels.

    Case-hardening and high carbon grades offer advantages across many applications. We exercise stringent control over chemical composition and production processes, resulting in a robust, consistent and reliable quality you can depend on.

    Heat-treatable steel

    Tata Steel offers a choice of hot-rolled heat-treatable steel. Its chemical composition and the production processes we employ ensure robust, consistent products. 

    Our case-hardening steel is suitable for wear-resistant components that must bear extreme fatigue stress. Our high-carbon grades supplied in the ‘as-rolled’ untreated condition can be processed to meet specific requirements.

    Overview

    Tata Steel offers a choice of hot-rolled heat treatable steel to suit a variety processing requirements and end applications. We exercise stringent control over chemical composition and production processes. This means our heat treatable steel is robust, offering consistent and reliable quality you can rely on. Please contact us with your exact requirements.

     

    Case-hardening steel

    Case-hardening grades provide excellent formability and good punching quality. Our case-hardening steel is suitable for wear-resistant components that must withstand extreme fatigue stress.

     

    High-carbon steel

    Hot-rolled high-carbon grades, supplied in the ‘as rolled’ untreated condition, are suitable for cold rolling to reduced thicknesses. They are often heat-treated to give the final mechanical properties required for the intended application.
    We offer two high-carbon grades to meet your processing needs.
